Fig. 6 is a detail view of a part of the construction shown in Fig. 2, showing a modification.

In Fig. 1 of the drawing, I have diagrammatically illustrated for the purpose of disclosing one use of my invention, the electric circuit of a radio receiving apparatus employing two radio amplification tubes 10 and 11, a detector 12 and two audio amplification tubes 13 and 14. In said figure, 15represents the antenna connection, 16 the ground connection, 17 the two phone terminals, 1.8 the plus 120-volt terminal, 19 the two terminals for the loud speaker, 20 the 45-volt plus terminal, 21 the A. plus-l3 minus terminal and 22 the A minus terminal. At 23,1 have diagram-' in atically illustrated my improved circuit control device, with which the circuit wires of the receiving apparatus, which is diagrammatically illustrated. are connected, the device 23 being shown in detail in Figs. 2, Sand 4 of the drawing.

My improved device comprises a yokeshaped or U-shaped frame 24 substantially similar to the jack frames commonly employed in apparatus of the class specifically described and rotatably mounted in i the frame 2 adjacent the crosshead 24? thereof is a shaft 25 to the outer end of which is secured an operating knob 26 having a pointer or indicator 27. Secured to the shaft 25 is a stop finger 28 which operates in an elongated aperture 24 inthe crosshead 24 to limit the rotary movement of the shaft 25. In the structure shown in Figs. 2 and 3 of the drawing a sleeve 29 of insulating material is secured to the shaft 25 within theframe 2a and fixed in and to said sleeve is a plurality of contact fingers 30 mount-ed in spaced relation and projecting radially from the sleeve 29 and in common alinement longitudinally thereof.

Mounted within the frame 24 above the shaft 25 is a block '31 of insulation material which is of the cross sectional form seen in Fig. 3 of the drawing, and mounted in and secured to said block are a plurality of pairs of contact disks 32, 33, 34,35. 36. 37 and 38, seven in number, which correspond in number with the number of Contact pins 30 employed in the sleeve 29. Said pins 30 are adapted to operate in and between the separate disks of each pair, the pairs of disks 32, 33 and 37 being constructed from the disk A shown in blank form in Fig. 5 of the drawing, while the disks in the cont-act 36 are constructed from the blank disk B, Fig. 5 of the drawing, the pair of disks 35 being constructed from the blank disk C in said figure, while the pairs of disks 34 and 38 are constructed from the blank D same figure. Each of the blank disks, A, B, C and D have projecting finger at, 7), c and (Z which project through the top face of the block 31 when said disks are moon ed in position and are adapted to be bent over and upon contact plates as hereinafter described. The blank contact plates'arc also provided with apertures a, 7), c and (5 respectively, which serve to anchor said plates in the block 31 and in the construction shown, rods or bolts 39 are passed through these apertures and the block 31 as w ll as through the frame 24 to secure the block in position and to retain said plates in position. Each of the plates of the separate pairs of contact plates are provided with exposed contact surfaces a, b", c and respectively which project beyond the inner face of the block 31 as seen in Figs. 2 and 3 of the drawing, whereby the projecting portions of the pins 36 may contact therewith in successively completing the circuits through the several tubes of the radio receiving apparatus as will be apparent.

Secured to the block 31 and projecting above the top face thereof and at the opposite sides thereof are a plurality of terminals 40, 41, 42, 43, 44, 45, 46, 47, 48 and 49 having plates which extend respectively to the pairs of contact plates 3233, 32, 3435, 33, 36, 34, 37, 35, 38 and 36, 37 and 33, in the manner diagrammatically illustrated in Fig. 1 of the drawing, wherein it will be seen that the communication of the separate poles named in the respective order is with one of the plates in each pair. In other words, the terminal 40 is connected with one plate in the pair 32, while the terminal 41 is connected with the other plate in said pair, and further the terminal 40 is connected with one plate of the pair 33 while the terminal 43 is connected with the other plate in said pair, etc.

In Fig. 6 of the drawing, 1 have shown a slight modification, in which I substitute for the shaft a sleeve construction 25-29 shown in Figs. 2 and 3 of the drawing, a shaft 25 equivalent to the shaft 25 in operation, and instead of mounting the sleeve of insulating material on the shaft as before described. I provide radio apertures 50 in the shaft 25 and mount bushings of insulating material 5 therein and in said bushings are mounted contact pins 52 similar, in operation and use, in all respects to the pins 30, the pins being held in place by collars 53 thereon and nuts 54 as clearly seen It will be understood that any means of insulating the pins 30-52 may be employed, as well as any means for mounting; and insulating the separate pairs of contact plates, and the separate plates in each pair one from the other, the construction shown being only illustrative of one method of carry inn my invention into effect.

The operation of my improved device will l. e readily understood from the foregoing description when taken in connection with the accompanying drawing and the following; statement lVhen the circuit through the ra dio apparatus is shut off, the shaft 25 is rotated by the nob 26 to bring the contact pins 30 into POSi'ilOll diagrammatically shown in Fig. 1 of the drawing. lVheu it is desired to put the apparatus in operation to listen in through phones by contactwith the terminals 17, the pins 30 are moved into position to engage the contact faces Z) of the pair of contact disks 36, thus completing the circuit through the battery connections as will be seen, and putting all the tubes 10, 11 and 12 into operation. In advancing to the first stage of audio amplification, and in putt? 7 gr the tube 1.3 into operation, the contact pins 30 are moved into engagement with the contacts on the pairs of disks 32, 35 and 37 and out of contact with the contact members of the pairs of disks 33, thus breaking the connection to the phones and in advancing to the second amplification stage or in putting the tube 14 into operation, the pins 30 are moved into position to engage the contact faces of the pairs of disks 32, 34, 36, 37 and 38, and in this position, the circuit through the contact portions of the pair of disks 35 is broken in addition to the ln'eaking of the phone circuit as previously stated.

From the foregoing, it will be apparent that in a partial revolution of the knob 26 of the circuit controlling device 23, the entire receiving apparatus may be moved from a shut off position into a fully operating position, or position in which all of the tubes of the apparatus functioning, and it will be understood that any number of stages of amplification may be employed, the controlling device being constructed to suit the particular apparatus in connection with which the same is employed, the showing and description as herein set out being only illustrative of one method of carrying my invention into effect. It will also be apparent that my improved circuit controlling device is not necessarily limited for use in connection with radio receiving apparatus, the same may be employed in connection with any electric circuit wherein a. plurality of electric devices are employed, and it is desirable to control the several circuits from a point of unitary control instead of employing;- a multiplicity of switches, jacks or similar devices, and various other changes in and modifications of the construction herein shown and described maybe made within the scope of the appended claims without departing from the spirit of my invention or sacrificing,- its advantages.
